sPEcIFIcATIoN forming part of :letters Patent No. 690,761, dated January7, 1902. Application tiled October 3l, 1901. Serial No. 780.660. (Nomodel.)

To @ZZ whom it may concern: Y I Be it known that I, WILLIAM'R. OYLER, acitizen of the United States,residing at Akron, in the county of Summitand State of Ohio, have invented new anduseful Improvements in Plows, ofwhich the following is a specification.

This invention relates to plows, and especially to plows of that classhaving glass moldboards, and has for its object to provide such a plowwith a high landside, cutter, and a guard-stripor protector for theforward edge of the glass moldboard.

It also has for its object to Vprovide improved means for supporting andholding the glass moldboard in place.

To these ends my invention consists in the features and in theconstruction, combination, and arrangement of4 parts hereinafterdescribed, and particularly pointed out in the claims following thedescription, reference being had to the accompanyingV drawings, forminga part of this specification, wherein- Figure 1 is a View in sideelevation of my improved plow viewed from the share side. Fig. 2 is aview in rear elevation of the plow. Fig. 3 is a perspective view of theplow, the moldboard and plowshare being removed and the point disengagedfrom the landside. Fig. 4t is a detail perspective View of the glassmoldboard viewed from the inner or rear side. Fig. 5 is a horizontalsection taken on the line 5 5 of Fig. 2. Fig.A 6 is a detail view of oneof the washers andY its filling-block, and Fig. 7 is a detail viewillustrating the manner of securing the moldboard to the bed-plates..

Referring to the drawings, the numeral 1 indicates the plow-standard,and 2 the low landside bolted to the standard. Disposed above the lowlandside in the same vertical plane with the latter is the high landside3,

is much shorter than the low landside, as

shown, and at its rear edge inclines downward to the low landside. Theforward p0rtion of the high landside is extended forward Vformedintegral with the to form an integral cutter 5, the front edge of whichis sharpened to form a knife-edge 6 and extends nearlyfvertically.

The numeral 7 indicates the plow-point, having a straight side 8., whichforms a continuation of the low landside, the' adjacent edges of the lowlandside and straight side S of the point overlapping one another andrigidly secured together by bolts 9. The upper edge of the plow-point isprovided with a laterally-projecting 'flangev 10, which vforms a seatfor the reception of or overlaps the forward edge of the plowshare 11.The forward lower edge portion of the plow-p`oint is also provided witha lateral or horizontal v flange l2, as usual. The flanges 10 and 12 maybe plow-point or may be Welded thereto.

The numeral 11v indicates the share, of the usual shape, the forwardedge of which is fitted between the straight edge 8 of the point and theflange '10, and its upper edge is bolted to a brace presently to bedescribed. On the inner or land side of the cutter 5 is a rearwardly andupwardly inclined flange 14. The

ange 14 preferably consists of a relatively Y lstandard 1, and from itspoint of attachment to the standard said bed-plate extends rearwardlyand outwardA at an angle from the' standard and landsides. A brace 16 isattached at one end to the rear end of the bedplate 15 and at its otherend is 'bolted to the low landside. A corresponding bed-plate 17 isdisposed beneath the bed-plate 15, parallel withV the latter, and at itsfront end is bolted to the low landside and at its rear end is connectedto one end of a brace 18, the other end of the latter being bolted tothe 10W landside. The rear end of the bed-plate 17 is provided with anintegral upwardly-projecting eXtension 19, adapted to be connected tothe moldboard.

The numeral 2O indicates the glass moldboard,which is of the usual shapeor configuration, and the bed-plates 15 and 17 are shaped to conform tothe inner, rear, or convex side of the moldboard. On said inner, rear,or convex side of the moldboard are formed projecting lugs 21 and 22,square in cross-section, and each having formed therein a verticalperforation or pin-hole 23. Elongated slots 24 are formed in the upperbrace 15, in which thelugs 21 are adapted to be fitted, and a similarslot 25 is formed in the portion 19 of the lower brace 17 for thereception of the lug 22. To secure the moldboard in place, it is placedagainst the bed-plates 15 and 17 in sucha manner that its lugs'21 and 22will respectively project through the slots 24 and 25, while the frontedge of the glass moldboard will lie in rear of the guard-strip orflange 14 on the cutter. The moldboard is then thrust or moved bodilyforward, its lugs moving in the slots and its forward edge sliding underthe guard-strip 14E or between the latter and the inner face of thecutter. The moldboard isthen rigidly secured in place, as follows: Theslots 21 and 25 being longer than the lugs 2l and 22 to permit thelatter to move forward in said slots it becomes necessary to fill up theslots in rear of the lugs after the mol'dboard has been moved forwardinto place to lock the latter. This I accomplish by tting washers 26over each of the lugs 21 and 22, and the rear end of each of saidwashers is provided with an extension which is offset from the washerand is provided with a rectangular block 27. When the washer is fittedover one of the lugs 21 or 22, the block 27 fits in the end of the slot2-1- or 25 in rear of the lug and lls up the slot, thereby preventingthe lug from moving rearwardly in the slot, and hence holding themoldboard rigidly in place. Pins 28 are inserted in the pinholes in thelugs behind the washers and operate to securely lock the lugs inposition and hold the washers with their attached blocks in place. Itwill be understood that there is one such washer provided for each ofthe lugs on the moldboard. The lower edge of the moldboard overlaps thelower bed-plate 17 and lies flush with the upper edge of the share 11,which latter is bolted to the bed-plate'17 by bolts 29.

A brace 31 is preferably attached at one end to the rear end of thebed-plate 15 and at its other end is bolted to the under side of theplow-beam, the purpose of said brace being to stilfen the moldboard andthe bedplate 15.

Constructed as above described the high landside prevents the earth fromfalling into the central part of the plow or the furrow being plowed. Asset forth, the high landside and cutter are made in one integral plateof steel, and the cutter operates to cut the sod and roots and slice odthe earth from the land, while the guard-strip or pocket 14 protects theforward edge of the glass moldboard and prevents stones or the like fromengaging and chipping or fracturing the edge of the glass,

such stones or similar substances engaging and passing over the steelguard-strip and from the latter glancing off harmlessly over the smoothand polished face of the glass moldboard. Instead of forming theguardstrip separately from and welding, bolting, or riveting it to thecutter it will be manifest that it may be formed integrally with thecutter; but for the sake of convenience and economy of manufacture Iprefer to construct lthe guard-strip in the manner described.

It will be apparent that by removing the pins and washers from the lugs21 and 22 the moldboard may be readily removed, and the plowshare mayalso be quickly removed by merely taking out the two bolts 29. Theplow-point and high landside and cutter may also be quickly removed forrepairs and the like by detaching the bolts which secure these parts inplace.

I-Iaving described my invention= what I claim is y 1. In a plow,thecombination with the standard, low landside and share, of the highlandside and cutter consisting of a at metallic plate fastened tothe'standard, said plate eX- tending rearward of the standard to formthe high landside and extending forward of said standard and sharpenedon its front edge to form a cutter, substantially as described.
